Boiler body uses the forced circulation in the high temperature area to make sure all heating areas can be cooled down and avoid vaporization; The explosion door and flame detector are equipped for safe and reliable operation. Comb plates are used between both sides of boiler and tube bundle to avoid leakage of condensate and gas caused by using refractory concrete as sealing material. Air proof test is done before delivery in the factory to guarantee any gas leakage problem.

The steam generated in the boiler must be conveyed through pipework to the point where its heat energy is required. Initially there will be one or more main pipes, or ‘steam mains’, which carry steam from the boiler in the general direction of the steam using plant.

The Chernobyl disaster, also referred to as the Chernobyl accident, was a catastrophic nuclear accident. It occurred on 25–26 April 1986 in the No. 4 light water graphite moderated reactor at the Chernobyl Nuclear Power Plant near the now-abandoned town of Pripyat, in northern Ukrainian Soviet Socialist Republic, Soviet Union, approximately

The steam trap is fully open when the system starts up. Cold condensate and air are discharged. The opening and closing process is controlled by the interaction of the stage nozzle and the temperature sensor, which consists of duo stainless steel plates.

The Metal Magnetic Memory Method - a New Trend in Engineering Diagnostics. Traditional methods and means of diagnostics (ultrasonic inspection, magnetic particle inspection, X-ray) are oriented to detecting the already developed defects and by their designation can not prevent sudden fatigue damages of equipment, which are the main reasons of failures and sources of maintenance staff traumatism.
